Applied Nutrition Critical Oats

Critical Oats is a product from UK based company Applied Nutrition. This product states that it can be perfect for a Busy/Active Lifestyle This review will aim to examine the ingredients in this product to see if it can support the claims made.


100% Organic Wholegrain Oat Flakes

Ground Oats have been suggested to be key to lowering cholesterol (1). Other beneficial effects that ground oats provide include a reduction in blood sugar levels, heart disease and type 2 diabetes, more research is needed however to elucidate these effects.

Whey Protein Concentrate (Emulsifier Soy Lecithin)

Whey, soy and milk protein helps aid muscle protein synthesis when combined with resistance training (2, 3). Other key features include increasing muscle mass (4), an increase in lean body mass (5) and greater recovery from exercise (6). Longer periods of supplementation have shown greater gains in fat free mass (7).

Muscle protein synthesis is increased due to high concentration of Leucine (BCAA) which is a signalling molecule needed to increase muscle protein synthesis (8). Consumption of whey protein helps increase muscle mass due to a greater amount of peripheral nitrogen retention whereas soy protein has been found to have a greater effect on splanchnic protein synthesis (9).

The reason for greater recovery of exercise can be due to a post exercise insulin response (10, 11) which means glycogen resynthesis occurs rapidly so exercise can be prolonged, with greater training volume increased hypertrophy and decreased muscle damage.

Milk Whey Protein Isolate

Much like Whey protein, Casein is formed from milk during the cheese making process. Once separated, Acids are added separated from whey protein and formed into a solid state. Unlike whey; casein protein takes much longer to digest and has beneficial effects during the recovery process helping to rebuild muscle post exercise, (12). 

Medium Chain Triglyceride (MCT Powder)

MCT is known as medium chain triglyceride. It has been suggested that it can aid fat burning which will help weight loss (13), however this has been disputed (14) and more research is needed to fully elucidate these findings.

Thickener (Xanthan Gum) 

Xanthan Gum are water soluble dietary fibres, which have been reported to reduce total cholesterol; however there seems to be insufficient evidence to confirm this theory. (15)

Sweetener (Sucralose), Natural Sweetener (Stevia)

Sucralose is a sweetener that is calorie free. This ingredient is used in many products and is used to make the product taste sweeter and does not have any nutritional benefit.  

Stevia does not have any nutritional benefits as it is a sweetener and sugar substitute extracted from the leaves of the plant species Stevia rebaudiana
